1. What is the recommended maximum age for a sealed lead-acid backup battery used in a burglar alarm panel before scheduled replacement? → 3–5 years
2. What is the primary advantage of a recessed door contact over a surface-mount door contact? → Concealed installation that is tamper-resistant and aesthetically cleaner
3. Which best describes the scope of Vulnerability Assessment & Penetration Testing in professional practice? → A comprehensive area covering both theoretical foundations and practical applications
4. Which tool is commonly used to diagnose wiring faults in alarm systems? → Tone generator and probe
5. What component triggers an audible alarm when an intrusion is detected? → Siren
6. When installing an LTE cellular communicator in a metal equipment cabinet, what installation practice is critical for signal quality? → Mount the antenna outside the metal cabinet or use a remote antenna cable
7. Which standard governs the installation and performance requirements for power supplies used in burglar alarm control panels in the United States? → UL 681
8. What is the benefit of remote diagnostics for alarm systems? → Allows off-site troubleshooting
9. What is the purpose of intrusion detection systems (IDS)? → To monitor network traffic for suspicious activity and known threats
10. Which installation location is generally recommended to avoid for a PIR motion detector due to high false alarm risk? → Aimed directly at a heating vent, radiator, or air conditioning return
11. What is the recommended approach to staying current in Cloud Computing & Virtualization? → Regular professional development, industry publications, and peer collaboration
12. Which component is most likely to fail due to lightning or power surge? → Control panel
13. What is the recommended approach to staying current in Vulnerability Assessment & Penetration Testing? → Regular professional development, industry publications, and peer collaboration
14. Why is battery backup important in an alarm system? → To maintain operation during power failures
15. What does the UL listing require a burglar alarm power supply to do when AC power is lost? → Automatically switch to battery backup without interruption to the protected zone circuits
16. What is the purpose of a risk register? → To document, track, and manage all identified risks throughout a project or operation
17. Which best describes the scope of Cloud Computing & Virtualization in professional practice? → A comprehensive area covering both theoretical foundations and practical applications
18. A passive infrared detector is mounted in a corner of a 20×20 ft room. Which lens type provides the best 360-degree coverage from that mounting position? → Wide-angle or corner lens (up to 180°)
19. When selecting a glass break detector for a room, what is the maximum typical rated detection radius for most commercial acoustic glass break detectors? → 25 feet (7.6 m)
20. When testing a standby battery in an alarm panel, a technician measures 11.2 V under load. What does this indicate? → The battery is sulfated or failing and should be replaced
21. What is the role of a door position switch in access control? → Detects door status
22. What is a common sign that an alarm backup battery needs replacing? → Backup fails during outages
23. When installing a PIR detector in a room with large windows facing south, what environmental concern must be addressed? → Direct sunlight or reflected heat from HVAC vents can cause false alarms
24. What common challenge do professionals face when applying Database Management & Security principles? → Balancing theoretical best practices with practical constraints and real-world conditions
25. What common challenge do professionals face when applying Application Security & Development principles? → Balancing theoretical best practices with practical constraints and real-world conditions
26. What is the typical float charge voltage applied to a 12V sealed lead-acid alarm panel battery? → 13.5–13.8 V
27. What type of motion detector uses both microwave and passive infrared technology to reduce false alarms? → Dual-technology (dual-tech) detector
28. What does 'account duress code' refer to in central station operations? → A secondary password that silently alerts the central station the user is under coercion
29. Which document provides specific rules for fire alarm signal transmission? → NFPA 72
30. A seismic or vibration sensor is best suited for protecting which type of asset? → Vaults, safes, and ATMs against physical attack
